Modeling the growth of LT and TL-oriented fatigue cracks in longitudinally and transversely pre-strained Al 2524-T3 alloy
(2011-09-23)
The aluminum alloy 2524 (Al-Cu-Mg) was developed during the 90s mainly to be employed in aircraft fuselage panels, replacing the standard Al 2024. In the present analysis the fatigue crack growth (FCG) behavior of 2524-T3 ...

Inter-relationships among elastic constants for symmetrical or unsymmetrical laminates with cracked 90-plies
(Taylor & Francis, 2020-02-22)
The relations between the stiffness components of a symmetrical or unsymmetrical laminate having trans-verse matrix cracks only in the 90-degree laminas are explored in this work. The crack closure condition for these ...
Is there a crack epidemic among students in Brazil?: comments on media and public health issues
(Escola Nacional de Saúde Pública Sergio Arouca, Fundação Oswaldo Cruz, 2012-09-01)
In the past year, the Brazilian Federal Government and society have reported and acted on a crack use epidemic, which has been exacerbated by the media. This study hypothesized that crack use has not increased at the rate ...
Three-dimensional boundary element assessment of a fibre/matrix interface crack under transverse loading
(Elsevier, 2005-02-05)
The macroscopic behaviour of unidirectional fibre-reinforced-composite materials is strongly dependent on the strength of the fibre/matrix adhesion. The stress concentrations around the fibres lead to micro-crack initiation, ...

Inter-relationships among stiffness matrix components for general laminates with transverse cracks in oblique plies
(Springer, 2019-02-28)
In this paper, nine inter-relationships linking the stiffness matrix components of symmetrical or unsymmetrical laminates having transverse matrix cracks in some of the off-axis plies is presented. The crack closure condition ...
Boundary element analysis of three-dimensional interface cracks in transversely isotropic bimaterials using the Energy Domain Integral
(Trans Tech Publications, 2010-12-06)
It is presented in this paper a three-dimensional Boundary Element Method (BEM) implementation of the Energy Domain Integral for the fracture mechanical analysis of three-dimensional interface cracks in transversely isotropic ...
